Winds have pushed the smoke from the Aspen Fire, in the Sierra National Forrest, to the Sacramento region, causing a haze over the valley and concerns over air quality.

It prompted local air officials to issue a health caution for the entire Valley air basin, including San Joaquin and Stanislaus counties, and prompting them to monitor the fire and the smoke very closely.

Asthma sufferers like Carmichael resident Trish Masterson said the the effects of the smoke have affected her significantly. She has kept the windows closed, stayed indoors with her husband and canceled plans.

"It’s too much particulate matter for me to breathe, and I’ve spent too many days or evenings at the emergency room when I push it," Masterson said.

Particulate matter is currently at the “moderate” level for most of the Sacramento region, as indicated by the yellow in the Air Quality Index. When it reaches the orange designation of “Unhealthy for Sensitive Groups” is when air quality officials send out healthy warnings.

"These are thousands and thousands of acres, not just grassland, so they create enormous amounts of smoke," said Christina Ragsdale, a spokesperson for the Sacramento Air Quality Management District, referring to the Aspen Fire as well as the wildfires burning in Oregon.

"When those get into upper level winds they can travel a very long way," she said.

"If you have asthma or any kind of lung problem, heart problems or any other systemic health problems – or you're just concerned – you should call your doctor," Ragsdale cautioned.

The Aspen Fire has burned more than 14,000 acres and is only 30 percent contained as of Tuesday night.

The ozone was at "good" for most of the Sacramento region Tuesday, except for the Rio Vista and Placerville areas. They reached the orange level, which is "Unhealthy for Sensitive Groups."
